Abstract

Use of a multi-component resin system for fastening one or more fasteners in a substrate using a multi-component resin system containing one or more finely-divided gases in at least one of its components, wherein only the materials or mixtures presented in containers or chambers are components to be understood.

Description

  • The invention relates to the use of multi-component resin systems, hereinafter often referred to only as Kunstharzsytem €, for fixing fasteners.
  • It is known to use multi-component synthetic mortars, such as epoxy or polyurethane resin systems or radically curing Kunstharzsyysteme or the like, as fixing compounds in the construction sector, in particular as an adhesive for anchoring elements. Such mortar systems can be found for example in the EP 1 429 155 A2 , From the DE 196 41 68 A on the other lapping agents are known, which may contain gas bubbles in addition to diamond powder. From the JP 2002 003724 A Insulator coatings are known, and from the JP 2005-246235 A porous films as resistors, each containing gas bubbles.
  • As simple as the handling of such multi-component synthetic mortar in practice - for example, when used in the form of multi-chamber cartridges with static mixer, multi-chamber cartridges or pouches or other multi-chamber systems - it would still be desirable further simplifications, such as a further improved flowability during discharge for reduction the squeezing force and the pressure required for the filling of the containers in the production, reduced amounts of material and the like. In particular, the often required high extrusion force can lead to fatigue in the user and can affect the acceptance of such systems. In order to lower the price of such systems, as well as to improve the shrinkage properties, it is usual to provide a large proportion of fillers - but at the price that the presses, e.g. Increases the force required from cartridges and the stability (creep, drainage and drip resistance) decreases due to the increasing density and thus the stronger effect of gravity. The latter can be very disadvantageous, especially when used in hollow blocks in connection with screen sleeves. Thickening agents may also be added in addition or as an alternative - although the stability increases, but again with the disadvantage that the squeezability suffers. So there is always a dilemma - between expressibility on the one hand and stability on the other.
  • The object of the invention is therefore to provide new multicomponent synthetic resin systems for use in fastening fasteners which have improved properties, in particular with regard to the properties mentioned in the preceding paragraph, especially in the direction of lower density, smaller necessary extrusion force and / or improved stability , as well as finding ways to improve such properties.
  • Usually, the masses of known such resin systems are virtually completely deaerated at the latest before the final packaging, since above all - even macroscopically, e.g. As air bubbles visible - gas inclusions are considered to be annoying and can lead to segregation or other inhomogeneities.
  • It has now surprisingly been found that the presence of gases or gas mixtures, such as air, in particular in finely divided, preferably in atomic, molecular and / or fine (eg micro) -disperser form, can not only be tolerated in such fixing compounds, but even can lead to improvements in the stability and / or the pressability, so that an improved handling can be found. The abovementioned dilemmas can thus be overcome, surprisingly, at the same time the stability and the ability to be pressed out can be increased at the same time. Other important mechanical properties such as the tensile strength and pull-out force of anchoring elements from holes in a substrate are not or not significantly affected. A positive effect is that the corresponding synthetic resin systems also weigh less with the same volume (lower density) and thus less material input is necessary for achieving a good fastening effect. Surprisingly, the synthetic resin systems which can be used according to the invention are also outstandingly storable, without the occurrence of segregation phenomena such as bubbling or partial or complete separation of gas and other components. Shelf life can be further improved by adding foam stabilizers.
  • The invention thus relates to the use of a multicomponent synthetic resin system mentioned above, which contains at least one of its components one or more (preferably atomically, molecularly and / or microdisperse distributed) finely divided gases, in particular air, with components only in containers or chambers submitted materials or mixtures are to be understood.
  • The distribution of the gas (s) may be advantageously stabilized by the addition of foam stabilizers (eg, silicone-containing or (particularly in certain industries, where desired) silicone-free foam stabilizers).
  • The synthetic resin systems used according to the invention can be prepared by a process for producing a multicomponent synthetic resin system for use according to the invention for fixing fastening elements, characterized in that one or more gases, such as air, are finely distributed, in particular dissolved, in at least one of the components of the synthetic resin system. or dispersed.

For example, the components may be a synthetic mortar (component (a)) and a hardener (component (b)). In addition to the polyreactive ingredients, other ingredients that promote solidification, such as mineral, solution or hydration solidifiable materials, such as cement, gypsum anhydride or hemihydrate, magnesia binder, phosphate binder, quicklime, waterglass, or silicate concrete, may also be included in one or more of the components and / or separate components and contribute to the solidification.

If desired, conventional fillers, in particular chalks, quartz flour, sand, polymer powder or the like, which may be added as powder, in granular form or in the form of shaped bodies, may be used as fillers, or others, such as, for example, US Pat WO 02/079341 and WO 02/079293 (which are hereby incorporated by reference), or mixtures thereof. The fillers can be provided in one or more components of a multicomponent synthetic resin system that can be used according to the invention.
